Bill of materials' modeling: a proposal

Abstract

This paper suggests a new idea to form a Bill of Materials (BOM), for heavy equipment manufacturing companies, with the general concepts applied in others kind of manufacturing companies. The bill of materials, as an essential element of integration, from marketing to delivery, aims to facilitate the activities of Production Planning and of the Control System. The methodology developed is based on a new approach to build parallel bill of materials, using concepts of pseudo levels and assemblies, mainly based on the industrial organizational structure of the company and on the sequence of product fabrication in time. The implementation of this system for dedicated fixtures resulted in expressive reduction of lead time, project hours, fabrication hours and costs.
